Article 156 of Civil Code

1 - Annulment of the contract on grounds of duress may be sought by a person who consented to the contract under the influence of fear existing in his mind and induced without right, if that fear drove him to contract such that, but for it, he would not have concluded it in the manner to which he consented. 2 - Fear shall be considered to exist in the contracting party's mind if means of coercion were directed against him that made him apprehensive of grave harm threatening, or which he imagines to threaten, himself or any other person in respect of life, body, chastity, honour, or property. 3 - In assessing the existence of fear in the contracting party's mind, consideration shall be given to his being male or female, his age, his knowledge or ignorance, his health or illness, and every other circumstance capable of affecting the extent of the resulting fear in his mind.
